Databases by Clusters

STN database clusters contain databases covering the same subject area. You can search the clusters through the Multifile Search capability. Reviewing the clusters can help you determine which databases to search to find information on your topic of interest:

Others database clusters contain databases that share a similar feature (e.g. CAS Registry Numbers, numeric data, chemical structure searching) or have the same producer. All files in these clusters are also contained in the subject oriented clusters above.
